GEORGE W. MOORE, OF CHICAGO, ILLINOIS, ASSIGNOR TO MOORE ELECTRICCORPORATION, OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE.

MASSAGE-VIBRATOR.

To all whom t may concern:

Be it lmown that 1, GEORGE TW. MOORE, a citizen of the United States,and a resident of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements inMassage-Vibrators, of which the following is a specification.

My invention relates to improvements in massage vibrators, and has forits Object the provision of an improved construction of this charactercapable of operating substantially noiselessly, and which is of simpleconstruction and efficient in use.

Other obj ects will appear hereinafter.

The invention consists in the combinations andarrangements of partshereinafter described andv claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

' Figure 1, is a longitudinal section of a vibrator embodying theinvention,

Fig. 2, a transverse section taken through substantially the centralportion of the handle of the vibrator.

Fig. 3, a transverse section taken through the head of the vibrator, and

Fig. t, a transverse section taken through the extreme end of the handleportion of the vibrator.

The preferred form of construction comprises a hollow spherical head 5having a threaded stud 6 projecting from one side thereof and adapted toenter a threaded socket 7 in a contact piece or member 8, as indicated.The instrument is designed for use with various styles and types ofcontact members 8, all of which are made, however, in the usual manner,with a threaded socket 7 being detachably secured `on the head 5 asindicated. A combined handle and shaft bearing member 9 is arranged toproject from one side of the head 5 at substantially right angles to thestud 6, said handle member being detachably secured in a threadedopening 10 n the corresponding side of head 5, said handle member beingprovided with threads engaging the threads in opening 10 and with asealing flange 11 contacting with the surrounding sides of head 5 so asto seal the interior of said head against the escape of grease or otherlubricant with which the said head 5 is ordinarily filled.

Specification of Letters Patent.

Application filed November 4, 1918. Serial No. 260,921.

The handle member 9 is provided with a shaft bearing bore 12, which isenlarged near its outer end to form a larger bore 13, and anintermediate stop shoulder 14, as shown. An operating shaft 15 isarranged within the handle member 9 and is provided with lugs or ears 16stamped or struck up therefrom to contact with the shoulder 14 to limitthe inward movement of said shaft. At its inner end the shaft 15 isthreaded, and a vibrator weight 17 is secured eccentrically thereto torevolve within the hollow interior of head 5, the inner end of shaft 15being preferably upset to prevent accidental removal of said weight. Theweight 17 is of a size to pass freely through the opening 10, so thatthe parts may be readily assembled or taken apart when desired. By thisarrangement, all that is necessary to assemble the shaft and itscoperating parts is to drop the shaft through the bore 12 and secure theweight 17 to the inner end thereof, the lugs 16 contacting with shoulder14: and the weight 17 contacting with the inner end of handle 9 to holdsaid shaft in lace. At its outer end shaft l5 is made ho low andprovided with a longitudinal slot for engagement with the end of aflexible shaft in the usual manner forl operating the instrument. Alatch pin 19 is arranged in the side of handle member 5 projecting intothe bore 13 and adapted to engage a groove in the flexible shaft, in theusual manner, to prevent accidental disengagement of the flexible shaftbut to permit of ready engagement or disengagement thereof when desired.rlhe latch pin 19 is normally held in place by means of a wire spring 2Oin the form of a broken ring seated within a groove 21 provided inhandle member 5, as shown. By this arrangement, upon rapid rotation ofshaft 15, the eccentric weight 17 will cause corresponding vibrations ofthe contact member 8 carried by the head 5, thus providing the desiredvibrations for massage treatments of the face, scalp, or the like. Theinstrument operates practically noiselessly, and produces a character ofvibrations Well adapted to the use-intended. Owing to the lsimplicity ofthe form and arrangement of parts set forth, the instrument can be madewith great economy but is, nevertheless, strong, durable and efficientin use.

'While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariations and modifications without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.

Having described my invention, what I claim as new and desire to secureby Letters Patent is l. A vibrator comprising a hollow head; adetachable handle for said head; a shaft mounted in said handle andextending into said head, said shaft being mounted in said handle topermit of free outward longitudinal movement thereof but to prevent freeinward movement; and arrL eccentric weight removably secured to theinner end of said shaft, said weight serving to removably secure saidshaft in position in said handle, substantially as described. Y

2. A vibrator comprising a hollon7 head; a combined handle and shaftbearing removably secured to said head; a shaft bea-1'- ing extendingthrough said handle, the bore for said shaft being enlarged adjacent itsouter end to form a stop shoulder; a shaft mounted in said shaft bearingand provided with a stop contacting with said shoulder; and an eccentricweight threaded on the inner end of said shaft and contacting with theinner end of said handle, substantially as described.

3. A vibrator comprising a hollow spherical 'head having a threadedopening leading into one side thereof; a contact member mountingprojecting from another side of said head at substantially right anglesto the axis of .said opening; a combined handle and shaft bearingthreaded in said opening and provided with a flange for sealing thesame; a shaft bearing extending centrally through said handle, the borefor said shaft being enlarged adjacent its outer end to form a stopshoulder; a shaft mounted in said shaft bearing and having burs settherefrom to contact with said shoulder; and a Weight eccentricallymounted on the inner end of said shaft and revolving in said head,substantially as described.

4f. A vibrator comprising a hollow spherical head having a threadedopening leading into one side thereof; a contact member mountingprojecting from another side of said head at substantially right anglesto the axis of said opening; a combined handle and shaft bearingthreaded in said opening and provided with a flange for sealing thesame; a shaft bearing extending centrally through said handle, the borefor said shaft being enlarged adjacent its outer end to form a stopshoulder; a shaft mounted in said shaft bearing and having -burs settherefrom to contact with said shoulder; screw threads on the inner endof said shaft; and a weight threaded on said screw'threads andcontacting with the inner end of said handle, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

GEORGE W. MOORE.
